Preserving Ashéninka Perené with AI-Powered Speech-to-Text
Ashéninka Perené is an Arawakan language spoken by the Ashéninka people in the central Peruvian Amazon, primarily along the Perené River in the Junín region. With an estimated 5,000 to 10,000 speakers, it is considered vulnerable by UNESCO. The language is written in the Latin script, using an orthography developed by linguists and community members. Like many indigenous languages, Ashéninka Perené faces pressure from Spanish, the dominant national language, and younger generations are shifting away from it.
Accurate speech-to-text technology can play a crucial role in language revitalization. By transcribing audio recordings of elders, community meetings, and traditional stories, communities can create written archives that are searchable and shareable. Subtitles generated from transcriptions also make video content accessible to Ashéninka speakers who may have limited literacy in Spanish.
Specific Transcription Challenges
Ashéninka Perené presents several challenges for automatic speech recognition:
- Agglutinative morphology: Verbs can contain multiple affixes indicating person, tense, aspect, and mood. For example, "nokantavakari" means "I speak to him/her". The ASR model must segment these long words correctly.
- Prenasalized stops: Sounds like /mb/ and /nd/ are distinct from simple /b/ and /d/. Misrecognition can change meaning.
- Vowel length: Long and short vowels are phonemic (e.g., /a/ vs /aː/). The model must capture duration.
- Code-switching: Most speakers mix Ashéninka and Spanish frequently. The system must handle both languages in the same utterance.
- Limited data: Few transcribed hours exist for training. Speechyou uses transfer learning from related languages like Asháninka and Matsigenka.
Use Cases for Ashéninka Perené Transcription
- Oral history preservation: Record and transcribe interviews with elders to document traditional knowledge about plants, medicine, and rituals.
